EYELET-HOLE MACHINE.

SPECIFICATION forming part of Letters Patent No. 665,358, dated January 1, 1901.

Application filed October 30, 1896- Serial No. 610,528. KNo modem To all whom it may concern.-

Be it known that I, LEWIS T. ADAMS, of Whitman, in the county of Plymouth and State of Massachusetts, haveinvented certain new and useful Improvements in Machines for Punching Holes in Boot and Shoe Uppers, of which the following is a specification.

This invention relates to machines for punching holes along the edge of the upper of a boot or shoe for the insertion of eyelets.

The object of the invention is to provide a machine of this character which may be employed for punching eyelet-holes in uppers of different sizes and different styles in which "the holes should be differently spaced without removing and replacing any of the parts and merely by moving an operating-lever to one side or the other.

To this end the invention consists of a machine such as illustrated in the drawings and embodying those features of construction and arrangement which I shall now proceed to describe in detail and then point out in the claims hereto annexed.

Reference is to be had to the accompanying drawings, and to the characters marked thereon, forming a part of this specification, the

same characters designating the same parts or features, as the case may be, wherever they occur.

Of the drawings, Figure 1 is a plan view of a machine constructed in accordance with my invention. Fig. 2 is a front end. elevation of the same. Fig. 3 is a vertical longitudinal section on the line 3 3 of Fig. 1. Fig. 4 is a horizontal section on the line 4 4 of Fig. 3. Fig. 5 is a perspective view of one of the punching-blocks with a portion of the means for operating the punch. Fig. 6 is a longitudinal vertical section similar to that shown in Fig. 3 and showing the punch as having passed through a layer of uppers. Fig. 7 is a horizontal view on the line 7 7 of Fig. 6. Fig. 8 is a partial sectional view on the line 8 8 of Fig. 3. Fig. 9 is a vertical sectional view on the line 9 9 of Fig. 6. Fig. 10 shows an upper with differently-spaced eyelet-holes punched therein by my machine.

In carrying out my invention I employ a frame having a base a and side standards a, which are of the shape shown in Figs. 3 and 6 and which are connected at their upper ends by a cross-plate 0?, having a forwardlyprojecting shelf a and a vertical web a The standards are suitably braced by ribs Q The front edges of the standards are cut away, and the edges of the recesses are secured to a cross-brace 5, between which and the shelf a is placed a series of punch-blocks c. The rear ends of the punch-blocks lie between the cross-plate a and a cross-brace Z), supported by the standards a, said plate and brace acting as guides therefor. Each punch-block is of the shape shown in Figs. 3, 5, and 6that is to say, it is provided with two rearwardlyprojecting fingers 0, through which a pivotpin 0 passes and extends into slots (1 and b in the said plate a and cross-brace 1), respectively. The said slots are parallel longitudinally of the machine and guide the rear ends of the punching-blocks in parallelism when the latter are moved and are adjusted, as willbe hereinafter described, said pivotpins sliding in the slots to allow the blocks to move longitudinally, and said blocks swinging laterally around said pins.

The front end of each punching-block is cut away or recessed, so as to provide a forwardlyprojecting arm 0 to receive the punch d and its holder 01, the latter passing loosely through an aperture in said arm 0 as shown in Fig. 3, and an overhanging arm 0 to receive an anvil 6, against which the punch d is thrust by mechanism to be described.

On the shelf 0. is secured a forwardly-projecting platef by means of screws f, it hav ing a cam-slot f through which the anvil c in the punch-block loosely projects.

The slot f is peculiar in shape, being curved somewhat similarly to the curved edge of an upper, so that three of the anvils e are in a straight line, while the fourth one is removed from the line to quite a distance.

By removing the screws f the platef may be replaced by another one having a difierently-shapedcam-slot, the shape of the slot corresponding to the predetermined line in which the holes are to be punched. I

The holders d for the punchers dare each tubular in form, with a flanged base 61 and they rest upon a vertically reciprocatory crossbar g, being held in place thereon by an angle strip or guide 9, so that they are free to slide longitudinally as well as transversely of the said cross-bar g, while they are secured to it to reciprocate therewith.

Each punch is of the shape shown, having a shank (1 which fits in the enlarged opening in the upper end of the holder (1, with a flange cl resting on the top of the said holder, the upper portion of the punch being tapering in the usual way to provide a circular cutting edge.

The anvils each consist of a cylinder e, having a screw a threaded into its upper end and bearing against some relatively soft material e placed within the tube and in which the punch may embed itself. Projecting forwardly from the arm 0 of each of the punchbloeks is a pin 0 which enters one of a Series of slots h in a lever 7L, pivoted at 77/2 to one of the standards, said lever having a handle it adapted to be held in any position by a spring 7r, secured to the other standard by screws 71, h. The slots h in the lever converge downwardly and are of unequal length, each slot increasing in length according to its distance from the pivot 7L2, so that when the lever is operated the front ends of the punch-blocks are all brought nearer together in equal degrees. Now it will be seen that if the lever h is in its lowest position, as shown in Fig. 2, and is raised to its highest position the punch -blocks will all be shifted nearer together, the anvils e in the slot f serving to also shift the punch-blocks longitudinally as they are moved transversely or laterally by the said lever. The rear ends have no transverse movements, as the rod or pin 0 for each one acts as a pivot around which each is swung, the pin, however, sliding in the slots a and the punch-blocks being thus guided longitudinally and transversely by the slots a and f respectively. In other words, the punch-blocks are moved or adjusted obliquely of the cross-bar g by the lever 7L acting in conjunction with the aforesaid slots. Hence by raising or lowering the lever I am enabled to adjust the punches so that they may be employed for punching differently-spaced holes in uppers of different sizes and without removing any of the parts and substituting others therefor. If desired, however, the lever It may be removed by removing screw 7L3 and another one having differently-placed slots h inserted in its place.

The cross-bar g is provided wit-h two downwardly-projecting arms g 9 to receive the ends 1" t" of a forked operating-lever t'. The said front ends of the forked lever are pivoted to the arms by a cross-pin g and the rear end of the lever t' is connected by a bifurcated pitman-rod to a crank-pin t on a crank-shaft journaled in a bearing a in the rear end of the machine. The said crossshaft 1' is provided with a suitable drivingwheel 1' with stop devices 2' '5.

In order to vary the throw of the punches, the lever i is fulcrumed on a vertically-adjustable pin or fulcrum j, the ends of which are journaled in levers 7t 70, pivoted to the standards a by pivot-pins A set-screw k is threaded through the free end of a lever 70 and bears against the base a, so that by driving the screw down farther through the levers 7c the latter may be raised, carrying with them the fulcrum j, so as to vary the path of movement of the front end of the levers, as will be readily understood. The curved plate 1, having a gage Z and a series of enlarged apertures Z is secured to the standard between the arms c c of the punchblocks in a position to support a pile of uppers for the punches as the latter are raised by the lever i. Preferably the apertures Z are sufficiently large to receive punches irrespective of the positions occupied by the latter, so that the same work-plate may be employed for uppers of various sizes in which holes differently spaced are punched.

From the foregoing it will be observed that I have provided an extremelysimple machine by means of which Iam enabled to punch eyelet-holes which are relatively near together or far apart, as occasioned by the size of the upper, the adjustment of the punchblocks being effected by merely moving the handle 72. of the lever h. The adjustment of the punch-blocks is not only lateral, but said blocks are adjusted so as to conform to the curved edge of any size of upper.

Referring to Fig. 10, I have shown an upper in which the holes on one side, as at 2, are spaced relatively far apart for a largesized shoe, and on the other side, as at 3, are near together for a small shoe, both sets of holes being formed by my improved machine.
